Abstract (en)
[origin: EP0867733A2] In an optical member having a coating for reducing a ray reflecting on the coating and for reducing an electromagnetic wave incident on the coating, the optical member includes: a transparent substrate; and the coating including, and formed on the transparent substrate in the order named from the transparent substrate, a first light transmitting thin layer having a high refractive index, a first light transmitting thin layer having a low refractive index, a second light transmitting thin layer having a high refractive index, a second light transmitting thin layer having a low refractive index. At least one of the first light transmitting thin layer having the high refractive index and the second light transmitting thin layer having the high refractive index is a transparent conductive layer having a sheet resistivity of 100 OMEGA / &squ& or less.
